Don't have the black mask but I think they are probably close to the same in handling. Problem with the GT Academy version is no rear downforce. So when you are cresting the slight rise in the first lefthander at Grand Valley for example and hit the brakes, the rear end comes around and you're done like dinner. I've only tried a few laps tuning it but can't seem to do anything about it so I end up braking before the left hander a bit and then some more into the hairpin, which of course in an online race, might get you rear-ended because you brake before everyone else, or just passed.
If anyone knows how to tune this out of the car please let me know.
